For girls, yes. I have a total double standard. But I like so many girl names and need to scratch them off somehow. If this is a boy he will be William. And the popularity does bother me, but we've loved it for 9 years and it's after DH's grandfather, a classic name with many nickname options. So it is what it is.
Now, if it were trendy, or even definitely rising due to the surge in old fashioned names, then I'd keep looking.
